Is there a "reselect" option in Blender?
"In Blender, in edit and object mode, anyway, the key combination CTRL-Z is "undo"; the key combination CTRL-SHFT-Z is "redo". The undo history is accessed by the key combination CTRL-ALT-Z, listing the number of actions as defined by the user in the user preferences under the "Editing" tab, under the heading "Global Undo".

Additionally, SHFT-R repeats the last action.
